Review: I CRIED CUZ IT WORKED! - IT WORKED! Year before the pandemic, we've been dealing with a slow drain in our old home. We dont have plumber money so we've been putting up with the drain and using a plunger and/or plumr. This year its gotten so bad. Plumr was not working. Plunging stopped working eons ago (I shouldnt be surprised, ignoring small issues turns to big ones) So I've been trying so many brands and so many of their different items. Drano, Green Gobbler, other Plumr types of drain clog liquid. They all werent cutting it. Then in comes CLR. Directions say to use 2oz everyday overnight or when not in use for 7 days. Unfortunately I kept forgetting since tub always had water slowly draining in it or was being used. So i was only able to use it on weekends this month. This week though, the tub completely stopped draining. These past 3 days I've been forgoing a shower and doing the best I could. I was dying for a shower today. About 1/5 of the CLR was all I had, so I poured all of it in the clogged tub and prayed. It did work a lil, after an hour. Just in time for fam member to get ready for work. But drain was still slow. I come back to check for my turn after fam left for work and the drain was back to not draining at all. I later check a second time and see tub is still filled at same level. I broke. Insert frustration, crying inbetween trying to snake and plunger the drain for over an hour. Nothing, still the same amount of water. So I stop to go calm down for another hour and think of game plan to scoop out the water. As I'm about to go get a scoop, I hear a slow light gurgle increase to the most wonderful sound I havent heard in years. THE FAST GLUG GLUG OF DRAINING WATER IN THE BATHROOM TUB. I cried again watching the water quickly drain. Then turned on the faucet at full blast to rinse out the CLR and watched gloriously as the water disappered as quickly as it came out of the faucet. BUY THIS MIRACLE LIQUID. FOLLOW THE DIRECTIONS. AND DONT PROLONG THE DIRECTIONS LIKE I DID. Thank you CLR. I will buy more of this as preventative maintance now for my tub and all other drains in my home.
Review: My mom would recommend to help septic tank problems. - My mom was happy with this product, which I believe was recommended by her plumber. To help with her septic tank, she also uses one-ply tissue paper.

## Questions & Answers

**Q: So its not good for washing machines?**
A: We would not recommend it be used in a washing machine, it's meant to be used in drains to clear build-up caused by paper, food, grease, soaps, organic materials.

**Q: Does this work the same as Drano?**
A: This is to keep drain flowing not unclog.  More of a maintenance/preventive

**Q: I have hoses outside that connect to timers.   Over time, I guess due to calcium build up, they become stuck.   Which clr product would you recommend?**
A: We do not recommend using any of our products, effective in dissolving mineral deposits, on hoses as the chemicals effective in dissolving minerals are not compatible with the material of hoses (usually rubber or plastics). Our CLR Clears Pipes & Drains does not dissolve mineral deposits, rather it's formulated to dissolve paper, waste, food, grease, etc...normally found in household drains/pipes.

**Q: How much of the 42 oz. bottle do i have to use each month?  and, do i have to do my kitchen drain; each of my bathroom drains, etc. monthly?**
A: For best results apply during time of minimal water usage or overnight.

Slow Drains:
Apply 2 ounces per day directly into drain for 5 consecutive days or until drain flows freely.

Drain Preventative Maintenance:
Apply 3 ounces per month directly into each drain.
